It was kind of funny a year and a half ago when 9-year-old Semaj Booker bluffed his way past Sea-Tac Airport security, then sneaked on, not one, but two Southwest flights all the way to Dallas.

On his second attempt, Tuesday, it wasn’t funny anymore. This is looking less like derring-do than a pint-sized punk getting an early start on a career of petty crime.

Maybe the appearances on “Inside Edition” and “The Dr. Phil Show” went to his head. After that, maybe being just another 10-year-old seemed a little dull.

Whatever. Semaj got his 15 minutes of fame last year. Now he may be headed back to juvy and a lot more than 15 minutes in a place where the studio lights don’t shine.
